Heading Versus Tilt Chart for Assessing HGA Occlusion and Flop Risk in MSL Operations

The Mars Science Laboratory (MSL) high-gain antenna (HGA) sits low on the deck, leaving the sky occluded in many directions by other parts of the rover. Each drive must end with the rover at a heading where the Earth will be unoccluded during the next HGA...

EXOS Software

An improved version of EXOS software allows for the modeling of fabrics, mixtures, and porous materials, and also provides the ability to accept hex mesh geometries. The code employs a novel numerical method, a hybrid particle finite element approach, as well as particles and elements in tandem, each modeling distinct aspects of...
